2.6.1 Functional Description

The PR/SM LPAR Analysis inquiries allow you to track the
utilization and configuration of CECs and the LPARs into
which each complex is subdivided.  Any supported CA MICS
timespan and summarization pattern can be implemented.

Explanations of the terms used below in describing the
reports produced by these functions are presented in Section
2.6.4. A description of the controls available and how to
evaluate the effect of those controls with the PR/SM Analysis
reports is given in the standard output and PR/SM LPAR
concepts sections (see Sections 2.6.3 and 2.6.4).

Two available PR/SM reports are:

    o  CEC  Summary Report - This report can be produced for
       each user-selected CEC, tracking utilization and
       environmental measures.  The  percent of the  CEC
       consumed  by all  LPARs is reported to  provide an
       indication of whether additional LPARs can be absorbed
       by the complex and to aid in determining if the CEC is
       configured to achieve optimum throughput.  To aid in
       such analysis, CEC configuration information is  also
       reported.

    o  LPAR Activity Report - This report can be produced for
       each user selected logical partition, tracking
       utilization and environmental measures.  Utilization
       is shown in terms  of the percentage of the total CEC
       consumed by the LPAR, and the percentage of shared
       system and logical processor utilization for the LPAR.
       This allows for analysis of what load a given LPAR is
       placing on the entire CEC.  These measures enable you
       to analyze the load an LPAR is placing on the CEC.
       They also indicate whether additional processor
       resource should be allocated to a given LPAR, or
       whether they should be given up by this LPAR for use
       by other LPARs.  To aid in such analysis,
       configuration data is also reported.

Each report can be tailored during online definition to
display data at various timespans and summarization patterns
(reporting by zone, hour, or day, etc.).  Overall CEC Summary
analysis, as well as the activity of individual LPARs can be
tracked via these report.

These reports utilize information derived from the CA MICS
HARLPC file.  The range of data that can be reported from a
CA MICS database depends on the timespans that were defined
for the HARLPC file and the number of cycles defined in each
timespan.
